MicroPolar is the latest online moisture analyzer, using state-of-the-art microwave transmission technology.

MicroPolar is the latest online moisture analyzer, using state-of-the-art microwave transmission technology. The moisture measurement is carried out non-contacting, either on a conveyor belt or in a chute.

Without contact to the measured material, the sensors are not subject to wear and tear and even maintenance is not required at any time.
Typical fields of applications are to be found in the mining industry and power plants, in the chemical, pulp & paper and building materials industries.

Measuring Principle

The representative microwave transmission technology, penetrating the whole material cross-section, allows for the high accuracy and reliability of the system.

MicroPolar 2 LB 567 System Highlights

MicroPolar 2 LB 567 is predestined for applications with constant measuring conditions (e.g. constant particle size, bulk density etc.) The measurement is carried out without the need of a radiometric unit. In combination with a height sensor the system allows for a compensation of varying bulk heights on the conveyor belt. For more demanding applications however, we recommend to use the moisture sensor MicroPolar Moist LB 568

MicroPolar Moist LB 568 System Highlights

The moisture analyzer MicroPolar Moist LB 568 is applied when the bulk density varies. Beside the moisture measurement by microwaves the system comprises also a radiometric unit to measure the area weight (mass per unit area). By combining both measurements varying bulk densities can be reliably compensated leading to a significantly improved measurement accuracy.

Features of Microwave Moisture Analyzer LB 567/LB 568

Multi-frequency Technology

The measurement is performed with a number of different frequencies per measurement cycle, leading to a very stable and reliable measurement, unaffected by reflexes or resonances.

High Dynamics

The high dynamic range of Micro-Polar allows the precise determination of moisture on even very high bulk loads.

Height Compensation

If the bulk height varies, a separate distance sensor can be connected, ensuring highly accurate measuring results.

Area weight Compensation

Varying particle sizes can affect the measurement performance. Using the radiometric area weight compensation the fluctuating bulk density is reliable compensated and optimum measuring accuracy is achieved.

Reference Line

An integrated reference line makes the measurement independent from potential environmental influences.

Automatic on-site Calibration

The calibration is done directly on the evaluation unit. The software contains a sample taking feature, where laboratory values can be easily entered and linked to the corresponding measurement values. The calibration curve is calculated automatically.
